According to the German Weather Service DWD’s forest fire index, the risk is high to very high across much of the country until Tuesday.

The danger is greatest in the northeast where the highest warning level – level five, shown as dark red on the map – is in force in several places.

There are red level 4 areas in Lower Saxony, Bavaria, Baden-Württemberg, Hesse and Rhineland-Palatinate.

But levels of at least three are forecast for some regions of all of Germany’s states. 

Where are the fires at the moment?

The number of larger forest fires in Germany is manageable at the moment.

A fire on a former military training area near Jüterbog, south of Berlin has been burning since 31 May as wind keeps fanning the fire over the area, which is over 700 hectares.

This is not the first time the area south of Berlin has been affected by massive forest fires. In August 2018, over 600 people were evacuated from their homes after a fire broke out in the former military training area.

And last year there were more than 500 fires in forest-dense Brandenburg – the highest number in years.

A fire in a 50-hectare forest and moor area near Göldenitz, south of Rostock in Mecklenburg-Western Pomerania, has also been burning for a few days.

Why is the risk so high right now?

The lack of rain over the past few weeks in conjunction with high temperatures, wind and low humidity, can increase the risk of forest fires, according to DWD information.

Temperatures are well above 25C across much of Germany on Saturday.

The top layers of soil are bone dry in many places, said DWD agricultural meteorologist Andreas Brömser.

This applies to large parts of the north and east, but also to some areas in northern Baden-Württemberg, parts of Saarland, Franconia and the Upper Palatinate.

In some areas, the upper soil layers are as dry as they would usually be in August.

This situation is unlikely to change in the short term, either.

According to the DWD, there are no forecasts for persistent rain across the country.

It would need to rain for a prolonged period so that the water could soak through the bone-dry soil – dried-out soils can generally not absorb water quickly enough during short bursts of heavy rain.

Should you be worried about the impact on your health?

The high levels of smoke produced by forest fires can have health consequences, but if you can only smell the fire, it’s not a health risk at that point, said Torsten Bauer from the German Society for Pneumology and Respiratory Medicine.

Toxic gases and harmful soot are produced during combustion, but these only become dangerous when you can also see the smoke and fire, the lung specialist said. 

Those with lung or respiratory diseases, such as asthma, should be particularly careful as the pollutants can narrow the airways and soot can also cause lung damage.

So what should you do?

If there is a forest fire nearby, make sure you keep the windows closed.

What causes most forest fires?

Reckless behaviour plays a big part, according to experts.

“Campfires, barbecues or cigarette butts thrown away carelessly pose a high risk,” said Torge Brüning, fire protection engineer at R+V Versicherung.

Are there rules in place to help prevent fires?

Yes, there are strict rules in force across the country to protect forests. Open fires are strictly prohibited in all forests and nature reserves in Germany – with campfires, grills and camping stoves all falling under the ban. 

And, from March to October, there is also an absolute ban on smoking in forests across the country.

In some states, forests are smoke-free zones all year round. These include Brüning in Berlin, Brandenburg, Hesse, Mecklenburg-Western Pomerania, Rhineland-Palatinate, Saxony, Saxony-Anhalt and Thuringia.

Anyone who breaches the ban can expect to receive a hefty fine.
